today, selection painting is hard-coded.
all the UI properties from CSS-3 are implemented in gecko, so we should start
using them.
this has several parts:
(1) for every frame, selection must look at the nsStyleUserInterface part of the
nsStyleContext to determine if the frame is selectable or not
(2)if the frame is selectable, selection must ask the style context how to
render the selection.  possibilities include invert, system
highlight foreground/background colors, outline, etc.
(3) once selection respects style, we need to add proper defaults to UA.CSS and
possibly other style sheets like the edit non-wysiwyg style sheet.
For example, the syntax for allowing selection of visible named anchors would
a[name]: before {
  content : url(the_image_we_display);
  user-select : element;

the autocomplete stuff would probably be
whatever_acw_uses: before {
  user-select : none;

Peter will add some extra info about how to do this efficiently, how to protect
ourselves against style sheets causing reflows during selection (we'll
effectively forbid it), etc.

a reasonable default for us.css would be
:selection { background-color: Highlight; color: HighlightText; }
where Highlight and HighlightText should already implemented on all platforms to
get the system colors.  (See Rods if there is a platform where this is not
There would also be some !important properties added to this style rule to
prevent reflows during selection, peterl has details.

user-select property. Please advise and explain how this is my cup of tea.

Adding Need Info to status whiteboard - I don't understand the problem that is 
being reported, ergo I don't understand how I can fix it.

I'm getting the feeling that nobody cares about (or understands) this bug...

I need to know what it is about, why it was assigned to me, why it is important 
for beta3, and ONLY THEN can I actually do something with it. If there is no 
traction on this bug in the next few days it is getting closed.

This bug is outdated. We obey 'user-select', although not correcty yet (this is 
bug 42864 that I'm going to check in later today) and we also use the colors from 
the LookAndFeel, which gets them from the OS.

Marking fixed.
